I do not know if this have been done elsewhere before, or how hero minion factories has been used, but here is my take on using minion masters in the realms:

Basically, the point is to play the succer, with two minion masters and another support hero, in order to charm a black widow without the help of any other human player.
I've choosed to publish this under my wiki user page, but I'll appreciate any of your comments or observations (or flames) here.
Thanks,
Foo.
